摘　　要：介绍一种小温差相变蓄能设备及系统。该系统通过利用液体浸没相变材料进行传热的方式来减小换热温差,这种液体与相变材料不相容且密度差较大。在浸没状态下,换热温差很小,极大程度上缩小了相变蓄放能过程中的温差,可以使相变蓄能技术与热泵技术完美结合,达到节能减排的目的。This paper introduces a phase change energy storage equipment and system with small temperature difference.The system reduces the heat transfer temperature difference by immersing liquid into phase change materials for heat transfer.This liquid is incompatible with phase change materials and has a large density difference.In the submerged state,the heat exchange temperature difference is very small,which greatly reduces the temperature difference in the process of phase change energy storage and discharge,and can perfectly combine the phase change energy storage technology with the heat pump technology to achieve the purpose of energy conservation and emission reduction.
